| 6011 | Basic bearing designation | Standard metric bearing dimensions: 55mm bore × 90mm OD × 18mm width |
| HC5 | Hybrid Ceramic with Si3N4 balls | Enhanced high-speed performance, reduced friction, and electrical insulation properties |
| C3 | Radial internal clearance greater than normal | Accommodates thermal expansion, ideal for applications with temperature variations |
6011/HC5C3 Bearing Structural Features & Performance Benefits
Hybrid Ceramic Construction: The combination of chrome steel rings and Silicon Nitride balls provides significant advantages including 60% lower density, higher stiffness, and superior thermal stability compared to all-steel bearings. This construction enables limiting speeds up to 7,500 rpm while maintaining dimensional stability.
Optimized Internal Geometry: Precision-ground raceways and optimized ball complement ensure smooth operation and high radial load capacity (6,362 lbf dynamic / 4,766 lbf static). The deep groove geometry effectively handles both radial and moderate axial loads.
Enhanced Temperature Performance: With an operating temperature range of -30°C to 120°C, this bearing maintains consistent performance across diverse environmental conditions. The C3 clearance provides additional safety margin for thermal expansion.
Precision Manufacturing: Manufactured to ABEC 1 | ISO P0 tolerance class, this bearing ensures reliable performance in general precision applications while maintaining cost-effectiveness.
